This invention relates to a ratchet mechanism and has particularreference to such mechanism for use with fruit presses and the like.

The object of the invention is to provide improved ratchet mechanism forheavy duty.

Another object of the invention is to provide a ratchet mechanism whichis more easily operated than mechanisms of that type in use at thepresent day.

Another object of the invention is to provide a heavy duty ratchetmechanism which may have its parts cast requiring practically nofinishing of the parts.

16 Still another object of the invention is to provide a ratchetmechanism which may be readily and economically assembled and in whichthere are few moving parts so that there is little likelihood of thesame getting out of order.

According to the invention the ratchet mechanism comprises a suitablestandard having an oil groove which receives aball bearing, a ratchetwheel suitably mounted for rotation on said ball bearing, an operatinghead and cam actuated means for reciprocating said head for rotatingsaid ratchet wheel.

The drawings illustrate an embodiment of the invention and the viewstherein are as :0 follows:

Figure 1 is a side elevation of our improved ratchet mechanism,

Figure 2 is a top plan view of the same, showing the operating leverbroken away, Figure 3 is a vertical sectional viewtahen on the line 3-3of Figure 2,

Figure 4c is a horizontal sectional view taken on the line 44 of Figure1, and

Figure 5 is a horizontal section and may be said to be taken, asindicated, by the line 5-5 of Figure 3.

The ratchet mechanism is mounted on a standard 6 which comprises a base7, an upright inwardly tapering tubular post 8 and a ball bearinghousing 9 at the upper end of said post.

The outer wall 11 of said housing, together with the inner annularflange 12, form an annular cup 13 in which the lower race 14 and theballs 16 and upper race 17 of a ball bearing are housed.

Sufficient oil may be kept within this annular cup 13 to properlylubricate the bearmg.

The outer wall 11 of the housing 9 has a plurality otlugs 18 extendingupward therefrom and which said lugs are undercut at 19 for receivingthe head of a bolt 21 which secures a locking plate 22 onto said lug andonto the lower annular flange 23 of the ratchet wheel hub 24:.

The ratchet wheel hub 24, the ratchet wheel 26 and the standard 27 areintegrally formed and said standard is provided with an outwardlyextending flange'28 which provides a circumferential groove 29 betweenthe same and the upper face of said ratchet wheel.

This ratchet wheel is provided with an inner and outer circle of holes31 and 32, respectively, some of the Walls of which form abutments forengagement by the pawls 33, as later explained. v

The reciprocating head 34 whose width is almost equal to the diameter ofthe ratchet wheel 26 has a recess 36 formed midway of its length andalong the two sides of this recess are bearing pads 37 The bearing pads37 fit within the circumferential groove 29 provided bythe fiai'ige 28on the standard 27 and provide for the free and easy reciprocation ofthe head 34.- while always retaining the said head in aligned position.

The outer ends of the head are provided with upstanding lugs 38 whichhave oblong holes 39 in the same for receiving the pawls 33, while saidlugs terminate inwardly in upstanding wings 41 which, together withwings 42 on pads 43, provide means for retaining the ends of connectingrods 4% which are pivotally held in position by means of the pins 46.

The pads is are locatedbetween the lugs 38 and the bearing pads v37 andthese lugs are also provided with oblong holes 47 for receiving thepawls 33 when a greater speed of the ratchet wheel 26is desired.

The connecting rods 44 have their outer ends terminating in bearingrings 48. These bearing rings are adapted to receive eccentrics e9,carried rigidly upon shaft 51 which said shaft is journaled in bearings52 on the ends of arms 53 formed integrally with the said standard 6.

The arms 53 have an integrally formed brace 55 between the same andbeneath the bearings 52 formed thereon.

One of the eccentrics 48 has an operating member 54 secured thereto bymeans of bolts 56 and this member has integral outwardly extending arms57 terminating in sockets 58 for the reception of a lever or the likefor operating said disks.

When the operating member 54 is rotated, the eccentrics 49 will berotated in the bear ings 48 and, on account of their eccentricattachment to the shaft 51, will reciprocate the head 34 and when saidhead is drawn towards the shaft 51 the pawl 33 on the one side of saidhead will rotate the ratchet wheel 26 and when the connecting arms 44move the said head away from the shaft 51, the other pawl will alsorotate the ratchet wheel in the same direction.

It therefore follows that for each complete revolution of the disk 49the ratchet wheel will receive two operating impulses. The bottoms ofthe pawls are tapered and operate in precisely the same manner as thepawls shown in the patent of Raifaele Baccellieri, one of theco-inventors herein, No. 1,513,209, granted October 28, 1924.

It is obvious that at the initiation of operation, the ratchet wheel 26may be rotated by hand, that is to say, by grasping the periphery of thewheel and turning it. As the resistance becomes greater, the ratchetmechanism may be availed of by inserting the pawls 33 in the openings ofthe pads 43 and in engagement with the inner circle of holes 31. Thereciprocation of the headwill rotate the wheel 26 with some rapidity. Asthe resistance again increases, these pawls 33 may be moved to theopenings 39 in the extreme ends of the head 34 to engage the outercircle of holes 32 which provide for greater leverage than operating inconjunction with the inner circle of holes 31.

It will also be seen that if the operating member 54 is oscillated backand forth, subscribing an arc of 90, the ratchet wheel will likewise berotated in the same manner and the double-ended socket operating memberwill permit of two persons operating the ratchet wheel in the mannerlast indicated.

The ratchet wheel hub has an axial bore 59 threaded so as to receive ascrew which is fastened to any suitable compressing de vice located onthe bottom of the same.

This screw and compressing member have not been shown as they form nopart of this invention, but may be the same as indicated in the patentabove mentioned.

This ratchet mechanism is intended for heavy service and the parts aremade sturdy so as to withstand all strains which may be produced by twostrong men handling the operating member 54.
